Product Description
Mitsubishi Universal model Redundant Power Supply Module Q68TD-G-H02
Q68TD-G-H02 Description
The Q68TD-G-H02 is an 8‑channel, fully isolated thermocouple input module designed for programmable controller systems, providing high‑accuracy temperature data acquisition for industrial process control. It accepts B, R, S, K, E, J, T, N‑type thermocouples conforming to JIS and IEC standards, converting analog temperature signals into 16‑bit signed digital values for direct controller processing. With channel‑to‑channel isolation, built‑in cold‑junction compensation, and disconnection detection, it ensures stable, noise‑resistant temperature monitoring in harsh industrial environments.
Q68TD-G-H02 Key Features
- 8‑Channel Isolated Input: Transformer isolation between channels eliminates crosstalk and ground loop interference.
- Multi‑Thermocouple Support: Compatible with B, R, S, K, E, J, T, N types for wide temperature ranges (−270 °C to +1,820 °C).
- High Resolution: 0.1 °C (K/E/J/T types) or 0.3 °C (B/R/S/N types) resolution for precise measurements.
- Fast Conversion: 640 ms/8 channels conversion speed; 320 ms sampling cycle for real‑time data.
- Cold‑Junction Compensation: Integrated compensation with ±1.0 °C accuracy for accurate readings.
- Disconnection Detection: Per‑channel open‑circuit alarm for fault diagnostics.
- 16‑Bit Digital Output: Signed binary values (−2700 to 18200) for direct scaling and monitoring.
- Compact Single‑Slot Design: Space‑saving installation with standard 40‑pin connector.
- High Noise Immunity: Isolated design withstands electrical noise in process and manufacturing environments.
Q68TD-G-H02 Materials & Applications
Materials
- Housing: Flame‑retardant thermoplastic alloy (UL94 V‑0) for insulation and impact resistance.
- PCB: High‑temperature glass‑epoxy laminate with gold‑plated contacts for signal integrity.
- Connectors: 40‑pin nickel‑plated header (A6CON series compatible) for secure wiring.
- Internal Components: Conformal‑coated circuits for dust/moisture resistance; isolation transformers for channel separation.
- Bracket: Cold‑rolled steel with anti‑rust coating for mechanical stability.
Typical Applications
- Process Industries: Chemical, petrochemical, and pharmaceutical plants requiring multi‑point temperature monitoring.
- Manufacturing: Furnaces, heat treaters, and industrial ovens with precision thermal control.
- Power Generation: Boiler, turbine, and exhaust temperature monitoring in thermal power plants.
- Food & Beverage: Sterilization, fermentation, and storage temperature tracking.
- HVAC & Building Automation: Large‑scale facility temperature monitoring and control.
